I began to see strange issue with NFC.
I keep it enabled all the time but after phone goes sleep NFC often gets disabled.
So I look at settings but it says NFC enabled, despite this phone can't read NFC tags, even Google Pay won't work.
Only after I move slider to disabled then back to enabled NFC goes back to enabled state ... well until phone sleeps again.
Very annoying.
Anyone?

Hi,
I just discovered something strange: I use FolderSync to sync Music to my GN. I configured it to only sync when WLAN is available. When I sync and switch the screen of, then the Sync stops immediately and resumes when I switch the Screen back on. Is WLAN switched off when the screen is switched off? Did I miss some settings to configure that?
Thanks
May be related with some auto task killer or process killer like juice defender
Yes you missed some wifi settings. You can set there whether you want to turn off wifi with the screen, keep it always on or keep it always on while charging.
You can find it in:
Settings - wifi - ... - advanced
Thanks martan1981, but this is "always on" on my GN. So thats not the reason
Do you have any battery-saving apps like JuiceDefender or GreenPower installed? That could cause your data/wifi to turn off with the screen.
Or there could perhaps be a power-saving function built in to your ROM? I know AOKP has a Power Saver mode that could be enabled to turn data off with the screen.
wifi sleep policy should be set to never. But some people have a bug where this setting does not stick for some reason. You prob have this bug too.
I also have this problem how to fix it ?
No root stock 4.0.2
I have a Galaxy Note 4 on AT&T that I purchased about a week ago. Everything worked great up until today. I have been successfully using the fingerprint lock to keep my phone locked while I'm at work. Tonight, I unlocked it and went to disable the fingerprint lock, but now the "swipe" and "none" options are greyed out and disabled with "Turned off by administrator, encryption policy or credential storage" and won't allow me to disable it. I have not been tinkering with anything and have no idea how any of that stuff could have been enabled since the phone was just sitting in my desk at work.
So, how do I get that turned off so that I can disable my lock screen when I am at home or away from work?
Thanks!
it seems like you may have enabled other security features like.. encryption which does not allow you to turn off the lock screen.. try disabling these extra protection s

And how would I do that? I'm not seeing anything enabled on my phone. I may be missing something. And again, nothing had been changed from the previous week's use. I enabled the fingerprint lock on it, put the phone in my desk, and left it there. Once I got it back out, I was no longer able to disable the lock. I can unlock the phone, I just can't turn the lock off. Hopefully I'm just missing a setting somewhere and it will be easy to fix.
SOLVED
Well, I somehow managed to figure out the solution. It apparently had something to do with the credential storage. I found the settings for that and had my phone clear the credential storage. After that, I powered my phone off and back on and it started working normally.
Now, the next question. How did some app set credentials to where my screen unlock couldn't be turned off?
Having just returned to the latest stock firmware after a couple of weeks testing CM12.1, I am finding that even if I turn "Keep scanning on" off in advanced WiFi settings menu, it comes back on by itself. Also, when I check my battery stats, it nearly always seems to show a solid bar for WiFi regardless of whether my WiFi was turned on or not, regardless of whether always scanning is on or off, regardless of whether location is on or off... it seems to have no effect whatever the settings are.
I am also unable to use the Power Saver function. If I try to open it, I get the "Unfortunately power saver has stopped" message. I read that disabling the stock clock or calendar apps causes this problem, so I deliberately didn't do so. Are there any other stock apps that will stop power saver from working if disabled? I guess I may have to enable everything again and then disable one by one checking power saver each time to find the culprit, but that is a huge pain in the behind, so thought I'd ask you guys on xda first
Hi guys, I am using standard (unsecure) lock screen, but recently I often put the phone away when working, so I enabled PIN for unlocking the screen, and some options in Smart Lock settings (face recognition and location)... it works nice, but after only 8 hours of using Google Play Services used 40% of battery... When disabled PIN and Smart Lock, battery usage went down... Did anybody had similar issues? Is it possible they poor job on this part of system? I mean, I understand that for face recognition, camera must turn on for couple of seconds, and I guess for location services, device will refresh location more often then without this enabled, but my GPS is turned off...
Yes those features use more battery. Gps isn't the only location method. Wifi and cell towers are used too.
Battery guru may help. See the playstore.
Beamed in by telepathy.
it's too annoying
worst thing is that I can't set PIN to be requested after 5 minutes (or 3), and to enable lockscreen in the meantime. This way, I keep unlocking phone in my pocket
On android devices it was always possible to switch localisation services and GPS separately.
You could keep localisation services turned on (with wifi and phone) and turn off GPS to spare battery.
Now with android pie and new smasung settings it is all or nothing as there is onlys one setting :
I can turn on localisation and it turns on GPS
But if you turn it off, it disables everykind of localisation : GPS but also wiifi ...
Has anyone noticed this and is there a workaround ?
I'm not a fan of the always enabled GPS
I really do not like this at all. I have typically always kept GPS off as far back as Jellybean, favoring Locations battery saving mode, unless I needed navigation or something like that. GPS is power hungry and there's no reason to have to have it always enabled. I know Pie is supposed to help with battery usage and I honestly can't judge whether or not it really does yet as this is day two for me.
Pie is supposed to prevent apps from accessing sensors in the background but I've read that this doesn't apply to GPS so this whole thing is probably part of a marketing thing giving Google as well as app devs the ability to monetize ads based on specific location of us the users. Location is frequently wrong about where I am anyway, showing me a street over and even though I have WiFi and Bluetooth scanning enabled. As a result, my Safe Unlock no longer works when I'm home (only location I have enabled) which sucks. With Oreo I saw this somewhat often and only after I had been home for a while would the Safe Unlock work properly and I accepted this as a consequence of having Location in battery saving mode but now I'm not sure. I just no that with Pie, so far, Safe Unlock hasn't functioned once. My designated home WiFi that I'm on as I type should cause Safe Unlock to do it's thing but it's not. Maybe Location or Safe Unlock are broken. I have seen reports of both regarding Pie so I can't blame it in Samsung. I guess I'll have to try to figure out which of these features is broken.
I'm not sure if this is related to the Location issue but I also noticed that Samsung+ is not working for me. When I first tried to open it I got a notification that I need to have location enabled, I agreed (it was anyway), then I was shown a red screen with error or format codes that force closed faster than I could decipher it. This could be related or could have been broken in an update. Other than for ad purposes, and I don't recall seeing any other than Samsung ads in the Samsung app, I don't know why Samsung+ needs to access location services as it only works in the US and the network tells the app I'm in the US as well as the tower I'm accessing. I suppose it's another attempt to collect user info related to WiFi, Mac address and Bluetooth. I only got the "enable location" request the first couple of times I tried opening the app but the red error screen and FC both still occur. I tried to get a screenshot but I could only manage about half of the screen before it FC'd. I attached the partial pic. It's the bottom half of the screen. When it closes, the app window seems to slide up like when you close apps in the recents view. This brings up another complaint...Screenshot is slow to respond so events like this are next to impossible to capture. I'll have to get a camera out and try.

Yes I noticed this. I use 'Tasker' app as a workaround. I set Location Mode to High Accuracy when using Navigation apps, and set to Battery Saving after closing the Navigation app. You can also just create a widget on home screen to toggle Location Mode to High Accuracy or Battery Saving.
I confirmed this setting by using 'Power Toggles' app widget. When the GPS toggle in widget is highlighted, it means on High Accuracy mode, if not highlighted it's on Battery Saving mode.

I have yet to notice any adverse battery performance since I've been on pie and I've been on it since the start of the official betas. I was annoyed at first because I had always used battery save mode but really it's been a non issue for me.
